2005+ Mustang GT question on spark plugs
Like the title says. While my car is not running bad I can't help feeling that something is not right. My mpg sucks. I only have 12k, am running a moderate tune and while I drive aggressively at times I am not a maniac and am only getting 15 or so. I have read that fouled plugs can cause this issue. I haven't pulled them yet but will this weekend so I thought I would ask what I should look for.
